+1. Clone the repository: `git clone

+1. (🏁 first-time-only) Install dependencies:

+1. Build an optimized binary:
+
+- Clang: `./scripts/build.sh --compiler clang -t
+  release -m lto --prefix=$HOME/config/non-packaged`
+- GCC: `./scripts/build.sh -c gcc -t release
+  --prefix=$HOME/config/non-packaged`
+1. Build a debug binary:
+
+- Clang: `./scripts/build.sh --compiler clang -t debug
+  --prefix=$HOME/config/non-packaged`
+- GCC: `./scripts/build.sh -c gcc -t debug
+  --prefix=$HOME/config/non-packaged`
+1. Install: `make install`
+1. Set the emulation core type to ***normal*** by editing your config file
+  `dosbox -editconf` and setting `core = normal` in the `[cpu]` section.
+1. You may now run `dosbox` inside any directory in your Terminal.
+
+Note: `texture*` output is not available under Haiku; use the default
+`opengl*` output options instead.
